| 负离子光电子能谱已经成为探索光谱和化学动力学基础问题的最为重要的技术之一。本文简要介绍了负离子光电子能谱的发展历史，回顾了负离子光电子能谱发展过程中的几种主要技术，包括为了提高分辨率而开发出的零动能能谱和慢电子速度成像技术以及为在气相条件下研究多电荷负离子及其对应中性分子电子特性而开发的电喷雾源与负离子光电子能谱结合的技术。随后介绍其在锕系元素及化合物、含铍化合物的电子结构及成键特征研究中的应用及进展。 |
| 英文摘要: |
| Anion photoelectron spectroscopy (aPES) has become one of the most important techniques for exploring the fundamental problems of spectroscopy and chemical dynamics. In this paper, the development history of aPES and its applications in the study of electronic structures and bonding characteristics of actinide elements and compounds, beryllium-containing compounds are briefly reviewed. Several major techniques in the development of aPES including zero electron kinetic energy (ZEKE) and slow electron velocity-map imaging (SEVI) techniques to improve resolution are reviewed. Subsequently, the combination of electrospray ionization (ESI) source and aPES to study the electronic properties of multiply charged anions and their corresponding neutral molecules under gas phase conditions are introduced. The progress made in the study of the electronic structure and bonding properties of actinides and their compounds, beryllium-containing compounds by aPES are then discussed. |
